"HuckNroll.com sold its last item at 5:59am (Tuesday)," the company announced.

"We didn't close HuckNroll because we don't want to sell mountain bikes, we closed HuckNroll because we do, and we know that honing our and our customers' focus on Competitive Cyclist will ultimately be what's best for our customers," Brendan Quirk, general manager of Backcountry.com's bike division, said in a statement. Quirk founded CompetitiveCyclist, which Backcountry bought last year.
